GEORGE A. GRAESER, OF CHICAGO, ILLINOIS.

WATER-METER;

SiEEGIFICATION forming part of Letters Patent No. 400,331, dated March 26, issii.

Application filed July 9, 1888. Serial No. 279,374. (No model.)

To ZZZ whom it may concern.-

Be it known that I, GEORGE A. GRAESER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in ater-Meters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forminga part of this specification, in which Figure 1 is a side view of my improved meter as the same appears when connected with the usual service-pipes. Fig. 2 is an enlarged longitudinal sectional view; Fig. 3 is a bottom View taken upon the line a: :20, Fig. 2, viewed in the direction of the arrow there shown. Fig. 4 is a vertical sectional viewof the water-wheel and its surrounding parts and bearings; and Fig. 5 is an enlarged vertical sectional view of a portion of the inletpipe, showing my improved device for regulating the flow of water.

' Like letters of reference indicate like parts in the different figures.

The primary object of my invention is to provide a watermeter in which the flow through the induction-pipe to the water-wheel may be increased or diminished; or, if de-' sired, anon-metered passage maybe provided, whereby the meter may be gaged to deliver the exact quantity of liquid designated by the indicator.

A further object is to so construct a waterwheel in combination with deflectors that the flow of the water may act with constant unvarying and certain eiiect thereon, while the friction may be reduced to a minimum, all of which is hereinafter more particularly described, and definitely pointed out in the claim.

Referring to the drawings, A represents the case which contains the meter mechanism, and which is divided into three compartments by means of the intervening removable plates, at a, forming chambers B O D. A portion of the case A is separated from the main case, and is provided with a flange, a3, which is arranged to fit over the body of said main'case, to which it may be attached by means of screws or otherwise. Said part A is provided with a hinged cap, a to permit the dial a to be in spected.

Cast or formed, by preference upon the case A, are pipes E and F, the former ofwhich is the in duction-pipe and communicates directly with the meter-chamber, while the latter leads from the chamber 0. Ports 0 0, Figs. 2 and 3, serve as a communication between the chambers B 0, through which the water may flow to the eduction-pipe.

G is a duct which leads to the chamber 0 and communicates with the pipe E through a passage, g, which is adapted to be closed or opened by means of a screw-plug, G, tapped within a nipple, G Said screw is provided with a non-threaded extension, 9, the diameter of which is smaller than that of the opening through which it passes. The object of said extension g will be hereinafter more fully stated. To prevent leakage,'l provide a screw-cap, 9 which may be removed when it is found necessary to adjust the screw G.

Within the meter-chamber B, I place a wheel, H, preferably made from sheet metal, and provided with flat radial spokes h. Said wheel is mounted upon a shaft, h, which is placed upon a pivotal bearing adjustable by meansof a set-screw, 7t'-, tapped, into the botprovided with a series of depending paddles, 7L3, which rotate around an annular flange, b, formed upon the plate I), said flange serving as a guide whereby a channel may be formed in the line of the path of the paddles. It will be observed by reference to Fig. 3 that the line of the inlet and outlet pipes, respectively, is tangential to the circle described by the movement of the paddles. To serve as a deflector and secure the action of the water upon the paddles, I provide a plate, H, which is arranged parallel to the plane of the axes of the pipes E F, as shown in Fig. 3, and is rigidly attached to the plate (2. Within the chambers O D is arranged the usual clock mechanism, as represented, and which needs no description, to actuate the indicators upon the dial, and which is primarily driven by the wheel H.

The operation of said meter is as follows: Assuming the duct G to be closed by the plug tom plate, B, Figs. 2 and 4. 1 The wheel H is G, thereby causing all of the water to be directed through the metered chamber B, and that the indicator registers a flow of one hundred gallons during a given time, but that only ninety-five gallons by actual measurement is enabled to pass during that time, the discrepancy may be corrected by so regulating the screw G as to open a passage to the duct G sufficient to permit five gallons to flow through the unmetered chamber 0; but it may be found, even when the duct G is closed, that more water passes through the metered passage than is actually registered. In this event the plug "i" should be so screwed down that the projection g may enter the pipe E, as in. dicated in dotted lines in Fig. 2, and form an obstruction therein sufficient to diminish the flow of water, so that its volume may be corclaim, and desire to secure by Letters Patent, is

In a wateraneter, a metered and non-metered passage, the one comlnni'iicating with the indnetion-pipe and the other with a duct leading to said induction-pipe, in combination with a screw-plug arranged in said duct and having an extension, 9, in eon'nnunication with said induction-pipe, whereby said duct may be closed or opened at will or the waterpassage in the indnetion-pipe more or less obstructed, substantially as described.

In testimony whereof I have signed this specification, in the presence of two subscribing witnesses, this 18th day of June, 188

GEORGE A. GRAESER.
